The Outlast® differenceThe Geoff Anderson® Outlast® Micro Fleece Vest continuously interacts with the unique microclimate of your body and the environment to moderate temperature from being too hot or too cold to being just right.
The human body naturally sweats to cool the skin, reducing the ability of the clothing, to keep the body dry and comfortable. Outlast® technology, conversely, will keep individuals comfortable by absorbing body heat when too much is created, thereby diminishing the amount of moisture during outdoor activities.
Fit:The nature of the fabric will make the vest “fit like a glove”. Will fit under even tight-fitting jackets.
Under the microscope:Outlast® Adaptive Comfort products all contain patented Outlast® Thermocules™ phase change materials (PCM). The microcapsules are microscopic in size: 1,000s fit on a head of a pin (3 million per cm²).

Infrared pictures can clearly demonstrate how Outlast® Adaptive Comfort® materials work.
Due to basic physical laws, all bodies (humans, plants, objects) release energy in terms of thermal radiation. The higher the object’s temperature is, the more intensive the infrared radiation released.
A test was done with a pair of gloves. One glove was equipped with and the other one without Outlast® material. Each gloved hand was then laid on an ice block for five minutes.
The test illustrates how temperature changes can be reduced remarkably with Outlast® products.
